Extended Power via MDI TLV
The Extended Power via MDI TLV enables advanced PoE management between LLDP-MED endpoints
and network connectivity devices. Advertise the Extended Power via MDI on all ports that are connected
to an 802.3af powered, LLDP-MED endpoint device.
•Power Type—there are two possible power types: Power Sourcing Entity (PSE) or Power Device
(PD). The Dell Networking system is a PSE, which corresponds to a value of 0, based on the TIA-1057
specification.
• Power Source—there are two possible power sources: Primary and Backup. The Dell Networking
system is a Primary Power Source, which corresponds to a value of 1, based on the TIA-1057
specification.
• Power Priority—there are three possible priorities: Low, High, and Critical. On Dell Networking
systems, the default power priority is “High,” which corresponds to a value of 2 based on the
TIA-1057 specification. You can configure a different power priority through the CLI, Dell
Networking also honors the power priority value sent by the powered device. However, the CLI
configuration takes precedence.
• Power Value—Dell Networking advertises the maximum amount of power that can be supplied on the
port. By default it is 15.4W, which corresponds to a Power Value of 130, based on the TIA-1057
specification. You can advertise a different Power Value using the
max-milliwatts option with the power
inline auto
| static command. Dell Networking also honors the power value (power requirement) sent
by the powered device when the port is configured for
power inline auto.

7 Streaming Video Specify this application type for broadcast or multicast based video content distribution
and other similar applications supporting streaming video services. This does not
include video applications relying on TCP with buffering.
8 Video Signaling Specify this application type only if video control packets use a separate network
policy than video data.
